hi i'm new to this blazer thing. just bought an 87 k5 on tuesday. anyway, my auto hubs take a lot of reverseing to unlock. i have heard that these are very problematic. how hard is it to switch to lockouts? are wrans really any better than the rest? thanks, i will probably be on here asking a but load of questions since i WAS a jeep guy for years and dont really know squat about blazers.
